摘要： A method to form a surface on a metal work piece includes providing a turning insert having a first cutting edge, a second cutting edge and a convex nose cutting edge connecting the first and second cutting edges, a nose angle formed between the first and second cutting edges being less than or equal to 85°; arranging the second cutting edge such that it forms a back clearance angle of more than 90° in a feed direction; positioning all parts of the turning insert ahead of the nose cutting edge in the feed direction; rotating the metal work piece around a rotational axis in a first direction; and moving the turning insert in a direction parallel to or at an angle less than 45° relative to the rotational axis, such that the surface at least partly is formed by the nose cutting edge.

摘要： A cutting tool has an insert holder with an indexable cutting insert removably secured therein. The cutting insert has upper and lower end surfaces with a peripheral side surface and a through bore extending therebetween, and a plurality of upper cutting edges formed on an upper peripheral edge. The peripheral side surface includes a non-circular upper relief surface adjacent the upper peripheral edge and a circular upper abutment surface spaced apart from the upper peripheral edge. Each upper cutting edge exhibits mirror symmetry about a bisector plane, and is non-linear in a side view. The through bore has an inner undercut formed by upper and lower bore surfaces located on opposite sides of a median plane, and a clamping member makes contact with one of the upper and lower bore surfaces at an inner contact zone located between the median plane and a seat surface of the insert holder.

摘要： A cutting insert of one aspect includes a top surface including a first corner portion and a second corner portion; and a top cutting edge. The top cutting edge includes a first corner cutting edge, a first major cutting edge, a second corner cutting edge, and a second major cutting edge. The top surface includes a first breaker protrusion and a second breaker protrusion. A gap between the first breaker protrusion and the first corner cutting edge is larger than a gap between the second breaker protrusion and the second corner cutting edge in a top view, a gap between the first breaker protrusion and the first major cutting edge becomes larger as a distance from the first corner cutting edge increases, and a gap between the second breaker protrusion and the second major cutting edge becomes smaller as a distance from the second corner cutting edge increases.

摘要： A cutting insert according to an embodiment of the present invention has a body section and a cutting section located closer to a front end side than the body section. The cutting section has an end cutting edge located along an intersection of an upper surface and a side surface, a recess located from the end cutting edge toward the body section, and a pair of protrusions opposed to each other with the recess interposed therebetween. The pair of protrusions has a first protrusion and a second protrusion located on the first protrusion. The first protrusion has a first inclined surface that is inclined upward and approaches another one of the pair of protrusions as going from the front end side toward the rear end side. A periphery of the second protrusion which is close to the front end side has a convex curvilinear shape in a top view.
